JPH0648908A - Method for exterminating blight and insect pest of plant and apparatus therefor - Google Patents

Abstract

PURPOSE:To exterminate blight and insect pest of a plant by spraying a treating liquid produced by making ozone absorbed in an acidic ion water. CONSTITUTION:Ozone is absorbed in an acidic ion water of pH 4-6 at a rate of about 0.05-0.5mg/L and the obtained treating liquid is sprayed to a plant to exterminate blight and insect pest of the plant. The treating liquid can be prepared by placing an ozone-mixing apparatus between an outlet part of the acidic ion water generated by an electrolyzing apparatus and a spraying means and the prepared treating liquid is sprayed with a spraying means via a storage means. The acidity of the acidic ion water can be lowered because the fungicidal and insecticidal actions of acidic ion water are increased by the proper application of the strong fungicidal and insecticidal actions of ozone. The acidic ionized state can extremely easily be maintained. An excellent plant-growing environment can be attained by the actions of the acidic ion water to promote the heal of wound and to improve the water-absorption of cell in combination with the action of ozone water to improve the water-retainability of cell.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest control technique for controlling plant pathogens and pests.

[0002]

2. Description of the Related Art Generally, pesticides are sprayed to control plant pests such as powdery mildew, downy mildew and spider mites. However, the spraying of this pesticide not only poses a health hazard to the sprayer himself, but also entails the risk of environmental destruction, which destroys the natural ecosystem.
As an example of the former case, health problems for workers in a closed space pose a serious problem, especially in the case of greenhouse cultivation. In this case, the problem arises that the work is cramped and the work is very hard due to the heavy equipment for defense. Further, as the latter example, a problem of natural destruction due to residual agricultural chemicals due to large-scale spraying of agricultural chemicals at golf courses and the like, which has recently been frequently raised, is exemplified. On the other hand, sterilization and insecticidal action of acidic ionized water may be used as an alternative to pesticides, but strong acidity, pH 2.5 to 3, is required for that purpose.
However, it is not only technically difficult to disperse evenly while maintaining this strong acidic ion state, the cost and maintenance of the device are expensive, and it is not easy for the human body and the natural environment. there were. It is also possible to use the sterilization and insecticidal action of ozone, but this method using ozone can be expected to have sterilization and insecticidal effects, but if the plant is damaged by pathogenic bacteria or pests, its strong oxidation By the action
On the contrary, there was a drawback that it hurt the healing of the wound.

[0003]

In view of such circumstances, the present invention solves the above-mentioned drawbacks of the prior art, and provides a method for exterminating pests of plants, a treatment liquid for extermination, and an extermination device which are friendly to humans and the environment. Its purpose is to provide.

[0004]

In order to solve the above-mentioned problems, the present invention provides a method according to claim 1, in which acidic ionized water is sprayed with a treatment liquid in which ozone is mixed and absorbed to control pests. In the invention according to claim 2, ozone is mixed and absorbed in acidic ionized water having a pH of 4 to 6 at a rate of about 0.05 to 0.5 mg / l as a treatment liquid for the extermination. The use of the thing, and claim 3
The invention described above is characterized in that a configuration in which an ozone mixing mechanism is connected between the outflow portion of the acidic ionized water from the electrolysis device and the spraying mechanism is used as the extermination device.

[0005]

As a result of the adoption of this technical means, the strong sterilization and insecticidal action of ozone is appropriately exerted to complement the sterilization and insecticidal action of acidic ionized water. Since the pH can be reduced to about 4 to 6, it becomes much easier to maintain the acidic ion state, and
This action of promoting the healing of wounds as ionized water of acidic ionized water not only eliminates the adverse effects of ozone on the healing of wounds of plants, but also enhances the water absorption capacity of cells having ionized water and the preservation of cells having ozone water. Due to the hydraulic power improving action, a desirable environment can be obtained from the viewpoint of plant growth.

EXAMPLES Examples of the present invention will be described below. FIG. 1 is a conceptual diagram showing a main part of an embodiment of the present invention.
In the figure, 1 is a raw water tank, and water obtained from an appropriate water source such as ground water or tap water is used as raw water. Reference numeral 2 is a filtering means, and an appropriate filtering means such as a biofilter is selected according to the type of the water source. 3 is an electrolyzer, which continuously produces acidic ionized water by an electrolyzer using a diaphragm method to obtain a pH of 4
It is configured to flow out as acidic ionized water in the range of ˜6. Reference numeral 4 denotes an ozone mixing device, which has a function of mixing and absorbing ozone at a ratio of about 0.05 to 0.5 mg / l with respect to acidic ionized water flowing into the device. Mixing of ozone obtained in this way
The absorbed acidic ionized water is sprayed on the target plants by the spraying mechanism 6 via the storage means 5 as a treatment liquid for controlling pests.

As described above, the treatment liquid for controlling pests of the present invention is composed of acidic ionized water in which ozone is mixed and absorbed, and the actions possessed by both are integrated,
It has an extremely good function as a treatment liquid for controlling pests of plants. That is, when this treatment liquid is sprayed on the target plant, first, the strong sterilization of ozone, the insecticidal action is effective within a short time of several tens of seconds, and the sterilization is carried out by the oxidizing power as acidic ionized water. , Insecticidal action will further enhance and maintain its effect. Further, in this case, by the action of promoting the healing of the acidic ionized water, the phenomenon of obstructing the natural healing of the wound of the plant due to ozone is alleviated to enable early healing, and the improvement of the water absorption capacity of the cells by the ionized water and A favorable growth environment is obtained in which the activation of plants is promoted in combination with the improvement of the water retention capacity of cells due to ozone. Further, the deodorizing effect of ozone and ions also improves the surrounding environment. The treatment liquid can also be used as bath water, humidifying water for a humidifier, cleaning water for a pool, irrigation water, etc., and is effective for sterilization, mold removal, deodorization, and the like.

[0008]

According to the present invention, the following effects can be obtained based on the above constitution. (1) Sterilization by the interaction between acidic ionized water and ozone,
By the insecticidal action and the healing promoting action, a good pest control effect can be obtained, and the effect of improving the water absorption capacity of cells as ion water and the effect of improving the water retention capacity of cells as ozone water are combined, and are good. A fostering environment can be obtained. (2) Moreover, acidic ionized water has low acidity, and if it falls to the ground, it loses its charge and returns to neutrality in a short time.
It does not harm the human body or the natural environment. Similarly, ozone does not harm the human body or the natural environment because it contains a small amount of ozone and decomposes in a short time to be released into the atmosphere as oxygen. (3) Also, since the acidity of acidic ionized water could be reduced,
It is easy to maintain the usage conditions, reduce the scale of the device, and reduce the corrosiveness, which facilitates maintenance of the device. Similarly, since the amount of ozone mixed in is very small, it is easy to make the mixed / absorbed state of acidic ionized water uniform, so that the apparatus can be made compact. (4) Further, particularly in pest control work in a closed space such as greenhouse cultivation, the work is greatly facilitated because it is released from wearing special protective clothing such as conventional pesticide spraying.
